I put a small 7lb pressure metal 12v fuel pump in series between the filter
and the stock fuel pump. A switch on the dash allows me to prime the system
and then shut it off, but it will also run the engine if the stock fuel
pump stops operating in case of flight emergency. I see no reason it can't
take over if the stock check valve fails, or the stock pump or pulse line
fails. I read that the fuel system is the number one cause of engine
stoppage. Gasohol uses plant-based alcohol and it eats rubber. The pump I
picked up at Autozone is made to run with gasohol, and doesn't restrict
flow when shut off.

I'm a firm believer in auxiliary electric fuel pumps.
When you mention pulse line failure (I assume for a two stroke), I don't
know how long that engine would run before it fails. A pulse line
failure would normally open the crank case to the atmosphere.
Anyone experienced a pulse line failure in flight?
Another reason for me to run premium neoprene fuel line, rather than
plastic "ultralight" tubing.

Should have added the following to my comment below:
"I don't know how long the engine would run before it fails "with an
auxiliary fuel pump".
